There is an increased interest in developing better user interfaces by means of different technologies because capabilities of user interface add a lot to the information technology (IT) adoption process. This book presents a study that develops taxonomy for the characteristics of technology adoption process. Besides, the study introduces a research framework that addresses how the product design features and various aspects of technology adoption process influence user preference and intention towards using a product. Proposed taxonomy and framework have been developed by series of observations: in-depth interviews, a brainstorming session, and an expert focus group. In order to test the proposed framework, an experimental study including a questionnaire was designed. Results of the study highlights the effects of product design features on user preferences and antecedents of user intention about using the product. These results will be important to developers who want to createinterfaces that stimulate mental processes of users, improve an effective, efficient, and intelligent machine interaction, facilitate user acceptance, and assist product utilization.
